Granted, I wasn't always such an at-home treatment enthusiast. The idea of a stranger massaging me in my tiny studio, for example, is too American Psycho to handle. And while the allure of private blowouts has tempted me once or twice, it always makes my place a mess—definitely not a hassle-free experience.

But the idea of someone coming to my door, 911-style, to replace chipped polish or fix my cuticles when I'm running to a party? Genius. Now, all I have to worry about is resisting the temptation of weekly appointments.
